AI Technical Summary
Technical Problem
Existing mounting architectures for acoustic protection screens in motor vehicles transmit significant vibrations from the vehicle's support to the screen, causing acoustic discomfort for passengers.
Method used
Incorporating a washer made of elastically compressible material, such as open-cell foam, between the fixing part and the screen's peripheral zone to attenuate vibration transmission.
Benefits of technology
Significantly increases transmission loss in medium and high frequencies, improving sound insulation by up to 13 dB and 5 dB respectively, compared to architectures without and with closed-cell foam washers.
